title = "Ionic crystal containing protons (H+) As counter cations: Preparation and crystal structure of a salt of 4,4¤-bipiperidine-1,1¤-diium and hexacyanidoferrate(II)",
abstract = "A molecular salt with a bulky cation and anion, (H2bipip)-(H)2[Fe(CN)6] (1) (H2bipip2+: 4,4¤-bipiperidine-1,1¤-diium), has been prepared. The salt comprises protons (H+) as counter cations. Single-crystal X-ray structure analysis revealed that the proton is trapped between two cyanido ligands of [Fe(CN)6]41 anions, forming a very short N£H+£N hydrogen bond.",
